Calcium carbide slag ndiyo marara akasara anoumbwa necalcium hydroxide mushure mekubviswa kwecalcium carbide kuti iwane acetylene gasi. Kugadzirwa kwemakemikari kubva kucarbide slag ndekwechinangwa chekudzokorodza zviwanikwa, uye kuvandudzwa kwemaitiro egirini uye kudzikiswa kwemitengo yetekinoroji ndiyo ichave nyaya yekutsvagisa mune ramangwana. HCMilling (Guilin Hongcheng) ikambani inogadzirakarusiyamu hydroxideslakinguyekarusiyamuchigayo chekukuya checarbonateZvishandiso zvinotevera zvichakuzivisai nezvemaitiro ekugadzira nano calcium carbonate kubva mucarbide slag.

Nano-calcium carbonate inoshandiswa zvakanyanya murabha, mapurasitiki, kugadzira mapepa, inki nedzimwe nzvimbo, dzine mukana mukuru wemusika. Muindasitiri, nzira yecarbonization inonyanya kushandiswa kugadzira nano-calcium carbonate, uye CaO inowanikwa ne calcining limestone, iyo inogayiwa uye inomiswa Ca(OH)2 Crush, kuwedzera crystal form control agent, pass CO2 carbonization, kushaya mvura mumuviri, uye kugadziriswa kwepamusoro kuti pave ne nano-calcium carbonate. Munguva iyi, marara gasi (CO2), marara emvura (mvura chena) uye marara akasara zvichagadzirwa, izvo zvichazopedzisira zvaita kuti pave nekudzikira kwemhando yechigadzirwa uye kuderedza kana kuita marara matatu. Zero emission uye kuvandudza mhando ye nano-calcium carbonate ndizvo zvinhu zvikuru, uye carbide slag inoenderana zvachose nepfungwa yekudzivirira zvakatipoteredza yekurapa marara nemarara.

Parizvino, kugadzirwa kwe nano-calcium carbonate kubva ku calcium carbide slag kunosanganisira nzira nhatu: calcination slaking, hydrochloric acid leaching uye ammonium chloride leaching. Li Rui nevamwe vake vakashandisa nzira ye calcination uye pressure slaking kuti calcium carbide slag iite ne CO2 flue gas mu pressurized carbonization reactor kuti iwane spherical nano calcium carbonate (60nm). Maitiro aya haangogadzirisi kusvibiswa kwe CO2 waste gas chete, asiwo anowana High value-added products; Liu Fei nevamwe vake vakatora hydrochloric acid leaching process, acidified calcium carbide slag ne hydrochloric acid ine pH=8, uye vakaita metathesis reaction ne sodium carbonate. Mhedzisiro yacho yakaratidza kuti acidified calcium carbide slag yaizosimudzira calcium carbonate whiskers. Kuitika kwe agglomeration uye coarse forked braces kunozopedzisira kwaita kuti aragonitic calcium carbonate whiskers ine uniform distribution uye high aspect ratio (30-60). Zvichienzaniswa nezvinhu zvakachena zvakanyanya, zvakaonekwa kuti nano-carbonic acid yakagadzirwa kubva kucalcium carbide slag. Calcium inosangana nezvinodiwa nenyika uye inoderedza kusvibiswa kunokonzerwa necarbide slag. Maitiro aya anoratidza nzira inoshanda yekugadzira nano-calcium carbonate.

Zhu Min nevamwe vakashandisa ammonium chloride kuti vagadzirise calcium carbide slag, uye vakazogadzira nano-calcium carbonate ne carbonization. Zvakabuda zvakaratidza kuti kana huwandu hwe ammonium chloride solution hwaive 8%, mwero wekushandiswa kwe calcium carbide slag waipfuura 92%. Mhando ye nano-calcium carbonate (avhareji yehukuru hwezvimedu i38nm), kuchena uye kuchena kwechigadzirwa chinowanikwa nemaitiro aya zvinosvika 99.65% uye 98.60% zvichiteerana, izvo zvinogadzirisa dambudziko rekuchena kushoma uye kuchena kusina kunaka kunokonzerwa nekusvibiswa kwe nano-calcium carbonate, uye mhinduro yakanaka kune mamwe mashandisirwo emaindasitiri. Nzira yakanaka yekushanda inopiwa.

Muchidimbu, huwandu hwakawanda hweCO2 hunoshandiswa mukugadzira calcium carbonate slag, uye kushandiswa kwakanyanya kwecalcium carbide slag kunogona kuitwa panguva imwe chete. Zvisinei, zviri nyore kugadzira mvura yakasviba kana pamusoro pacho pachichinjwa nemakemikari anowedzera. Kana ikasagadziriswa, inokonzera kusvibiswa kwechipiri. Zvinodiwa zvekutevera Kufunga kwakazara kunopiwa kune zvinokonzerwa nekuita kuti carbide slag idzokororwe.
